True handheld convenience for field work or
remote sensing!- SPECTRAL EVOLUTION
offers a PDA compatible version of its
DARWin SP Data Acquisition software that
permits fingertip control of mobile data and
can be used to trigger data collection
remotely. SPECTRAL EVOLUTION offers
the GETAC PS336 PDA preloaded with all
necessary software to run all Bluetooth
enabled SPECTRAL EVOLUTION
Spectrometers. The GETAC can be used to
tag spectra with GPS readings, photos (with
its built-in digital camera) and voice notes
with its built in microphone.
In this image, the PS336
was used to take a leaf
scan along with a photo
of the leaf.
Software capabilities for specific applications with
SPECTRAL EVOLUTION Spectrometers
Every SPECTRAL EVOLUTION Spectrometer and Spectroradiometer is supplied with the exclusive
DARWin SP Data Acquisition Module- a full-featured, menu driven program for easy data manipulation
and analysis of multiple UV-VIS-NIR spectra. The DARWin SP module features one-touch operation and
easy, intuitive menus for fast, effortless operation.

For added convenience, SPECTRAL EVOLUTION Spectrometers and Spectroradiometers may be
custom ordered with laptop computers preloaded with DARWin SP Data Acquisition software.
Depending upon your unique situation, we can put together a specialized computer package that takes
you application and portability needs into account. Contact us today for additional information.
SPECTRAL EVOLUTION also offers a Windows-based DARWin SP Data Acquisition software for use
with fully rugged handheld PDA devices. This program allows every SPECTRAL PDA. Contact us
today for additional information.
Leaf Reflectance: Rhododendron decorum (green trace) and Acer saccharum (red trace) leaf reflectance were measured using a
SPECTRAL EVOLUTION PSM-3500 Spectrometer with the companion SPECTRAL EVOLUTION ILM-105 Fiber Optic Illumination Module
fitted with an optional 1 meter bifurcated fiber optic cable. The graphs were generated using the easy-to-use DARWin SP Data Acquisition
and Analysis software included with each PSR-Series Spectroradiometer. DARWIN SP allows users to plot multiple scans on the same
graph for easy comparison and analysis. All units feature automatic exposure control and auto-shutter for simple operation.
Certain SPECTRAL EVOLUTION models designed for measuring solar radiance have capabilities for
calculating a spectral match report for measuring class performance as per IEC60904-9/ASTM
E927-05. This is especially useful for measuring the performance of continuous solar simulators. All
SPECTRAL EVOLUTION spectrometers can be used to measure CIE 1931 Colorimetry parameters.
All SPECTRAL EVOLUTION Spectroradiometers also come with a pull-down utility that allows users to
calculate integrated energy levels as a function of wavelength interval (user adjustable). An example of
this useful tool is shown below:

Certain SPECTRAL EVOLUTION models designed for soil & vegetative index measurements come with specialty
pulldown menus to automatically calculate 17 broadband and narrowband vegetative indicies (see pull-down
menu below). Each index can be user modified with simple on-screen menu-driven instructions.
Calculated indicies include:
NDVI (Normalized Difference Vegetation Index) GRVI (Green Ratio Vegetation Index)
SR (Simple Ratio Vegetation Index) DVI (Difference Vegetation Index)
SAVI (Soil Adjusted Vegetation Index) Red/Green (Red Green Ratio)
ARVI (Atmospherically Resistant Vegetation Index) Green NDVI (Green Normalized Difference Vegetation Index)
EVI (Enhanced Vegetation Index) MSAVI2 (Modified Soil Adjusted Vegetation Index Type II)
IPVI (Infrared Percentage Vegetation Index) Sum Green (Summed Green Vegetation Index)
PRI (Photochemical Reflectance Index) NDVI705 (Red Edge Normalized Vegetation Index)
WBI (Water Band Index) NDWI (Normalized Difference Water Index)
PAR (Photosynthetically Active Radiation) NDNI (Normalized Difference Nitrogen Index)
